Coincidentally I have been making these recently. I have done these but just put the dough in a large bread tin rather than making them into teacakes. I let the dough increase in size by 50% then baked in oven at about 200C for 40 minutes. Worked really well and was nice just sliced and buttered on the first day then toasted after that.

There's also a recipe in the GBBO Everyday book for marmalade teacakes which I made into a loaf as above. It tasted rather like panetonne but less rich. Also went down very well!
